click up a terminal and do a
man 2 read
man 2 write

If you look at the bottom of man pages you might see somethhing like
SEE ALSO
accept(2), bind(2), connect(2), fcntl(2), getpeername(2), getsock-

which indicates you may find more information by doing something like
man 2 connect.

Want to find code examples.

select() is the tool. man select, or Google.

Next time, please cross-post, if you really need to
post to multiple newsgroups. Now the responses from
different groups are separate, and much of the info
will be duplicated.
